FIDE finally published the list of teams for top division. According to regulations, top 25 automatically play in final stage (together with 15 teams which qualify from lower stage).

For the ranking FIDE uses the average places (Olympiad 2018, Women Olympiad 2018 and online Olympiad 2020). Canada is number 25, the last one!! That means we don't need to play in lower stage and start playing on Sep 8.
